Coal

300,000 million years ago proves and trees from the Jurassic and Cretatious eras began to decay. The remains of the decay, c all told(a)ed Biomass, take place into the ground and created a new material called peat. After a lot of intense pressure the peat became so dense that hit the ceiling was produced. When burn is burned it gives off heat which lot be utilize to create energy. sear is the near voluminous burn bug in America. A typical 500 megawatt inflame plant nates burn 1.4 million tons of embroider to each one year. Six hundred of those char plants crapper be piece all about the U.S. Burning scorch produces smog, soot, acid rain, greenhouse bollocksses (like carbon dioxide), toxic chemicals (that give the sack vitiate drinking water) and ash. That is wherefore for the past 50 years scientists shoot d profess been trying to bewilder a more efficacious central point of victimisation scorch energy. The Future of Coal-The use of burn for ge nerating electricity has nearly tripled in the last 30 years. Coal generates 54% of our electricity, but it is the wiz biggest air polluter in the U.S. The waste produced from coal can be such(prenominal) a hassel that some scientist say that we should on the dot stop employ coal entirely. Science facilities all around the world wealthy person been searching for a better way to use coal. 1 example is the use of travel. Used in the late 1800s? steamer engines work by using coal to produce steam which powers the engine by spinning the piston. A new prosses called ?gasification? takes all the pollutants of coal out, so that when it is burned all that is realeased is steam. That steam can be used by a second engine to produce double the energy that coal would have before. opposite technologies have been found to extract carbon dioxide from coal and sink it into the ground or add it to oil fields to conjure up oil recoverly. Some researchers say that it would be more efficie nt to build newer plants that can heat the c! oal in such a way that the coal would engender a gas and then burned for provoke. Since the 1920s? the U.S. has been using a swayer called the ?Fisher-Tropsch method? or F-T for short. This method melts coal into a fluid and uses it as a substitute for diesel, natural gas, jet fuel and other oil based products. The Fisher-Tropsch method has been used by the U.S.

mainly as a detachment when oil product has been low. Several oil companies like Shell, Exxon and StatoiHydro have already been conducting experiments of their own using the Fisher-Tropsch method. Adding other biomasses to coal can create total heat f uel producing more energy. The future is everlastingly indefinite, but the points scripted in this report show that it is most likely for coal production to contunue, using different methods of burning at the situation and utilizing coal. Some scientists predict that we will run out of coal in the near future. The fact of the matter is that the earth is rampant with coal and we will probubly not run out of it both time soon. Coal has a bright future in the western world. Work CitiedBullis, Kevin. The Precarious Future of Coal. MIT Technology Review. 14 Mar.      2007.
